Abstract
Autostereoscopic monitors allow spontaneous three-dimensional perception of the visualised content without the need of any additional viewing aids. Such a kind of spatial perception can also allow multiple new visualisation options in the field of cartography. So far, there are hardly any rules given for an optimal design of such cartographic visualisations. But, this is essential in order to use the potential of these 3D monitors correctly. Therefore, this work deals with the design of cartographic content on autostereoscopic monitors. Thus, it shall contribute to an optimal use of such a monitor for cartographic purposes in the near future.

After describing the state of research regarding 3D visualisation techniques and minimum dimensions of cartographic content on monitors in general, the present work discusses two empirical studies. In the first study, several graphic elements are analysed regarding their minimal legible size. Some lettering, lines and simple symbols are tested regarding their legibility on a monitor which uses the lenticular foil technology. The test patterns are based on existing recommendations for 2D monitors and studies on printed lenticular foil displays. A simple rule was chosen to be able to specify minimum sizes for the tested elements: at least 90 % of the test persons have been able to read the test words, lines or symbols in this size. Furthermore, the first study investigated the ability to differentiate several depth planes. With the help of point symbol blocks which are located in different distances to the viewer, i.e. which are located in different depth planes, it is examined if the participants can differentiate these planes easily. Altogether, nine pairs of hypotheses are analysed during this study.

The second empirical study which is presented in this work, deals with the map reading performance in thematic maps visualised on 2D monitors and on 3D monitors. Using thematic maps of simple design the response time and response accuracy are analysed for solving simple map reading tasks. The used 3D monitor was the same as for the first study. Further, the same questions were asked for the thematic maps shown on a normal 2D monitor with nearly the same size as the 3D monitor. In this second study two pairs of hypotheses are analysed. Moreover, the findings are compared with a similar study which was conducted at the Geographic Institute of the Ruhr University Bochum. The project partners tested the thematic maps on a second lenticular monitor under very similar conditions. Based on a comparison of both studies an attempt will be made to draw some conclusions that are generally valid for a design of cartographic content on lenticular monitors.
